Orientation & Congruence

Front

What is congruence in geometry?

Back

Congruence in geometry means that two figures have the same shape and size, allowing them to be superimposed on each other.

Front

What does it mean for an object to maintain orientation?

Back

Maintaining orientation means that the object's position and direction remain unchanged after a transformation.

Front

True or False: An object and its image maintain congruence if they are similar.

Back

False. Congruence requires exact size and shape, while similarity allows for proportional differences.

Front

True or False: An object and its image maintain orientation after translation.

Back

True. Translation moves an object without changing its orientation.

Front

True or False: An object and its image maintain orientation if corresponding sides are parallel.

Back

True. Parallel sides indicate that the orientation is preserved.

Front

True or False: An object and its image maintain orientation after rotation.

Back

False. Rotation can change the orientation of an object.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, including translations, rotations, reflections, and dilations.

Front

What is the difference between congruence and similarity?

Back

Congruence means figures are identical in shape and size, while similarity means figures have the same shape but may differ in size.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point at a certain angle.
